## Description

J-B Weld High Heat Epoxy Syringe, Dark Grey

Review: JB weld rocked engine oil pit. 5 stars - Does what it says. I am from India and probably this is the first review from Indian Standpoint. I broke my engine oil pit hitting a rocky bottom on the road, which made a dent in the sump. After researching much I found out this solution to fix break for temperatures outside normal epoxy range and to my wonders this works great. I sanded the surface as described, cleaned it with rubbing alcohol and pasted a mix of the solution. It looks rock solid and theres no leak as well.
